“…Plants remove ammonia nitrogen due to the stimulation of nitrifying bacteria and the uptake of nitrogen compounds [8], but these mechanisms seem to be marginal in many examples. Typha latifolia L. prefers slightly acidic environments, but ammonium uptake is conditioned by its toxicity (>0.2 g/L) [23] and COD concentrations of 0.6-0.8 g/L (that inhibit photo-synthesis and, consequently, nutrient incorporation) [23,58], as was evident in many stages of our study. Gonzales et al ( 2009) [36] stated that the macrophyte species did not significantly contribute to the overall efficiency of V-SSF CWs in N removal, especially in the dry season.…”

A Combined System Using Lagoons and Constructed Wetlands for Swine Wastewater Treatment

et al. 2021

This study evaluates the depuration efficiency of a combined system consisting of lagoons (with aerated and non-aerated tanks) and CWs (with Typha latifolia L.) working at pilot scale for treating SW under two recirculation rates (RRs, 4:1 and 10:1) of the CW effluent. The combined system removed about 99% of the total suspended solids and organic matter, and from 80% to 95% of the total nitrogen at both tested RRs. The lagoon system was effective as a pre-treatment of SW, particularly for nitrogen removal. It is convenient to adopt the higher RR, since nitrogen removal can be increased by approximately 20%. The irrigation of the CWs with SW did not generally determine the phyto-toxic effects on Typha latifolia L., except at the start of the experiment and under the lower RR. Despite the limited spatial and temporal scale of this investigation, these results provide a starting point for the use of V-SSF CWs to treat livestock wastewater with a high pollution potential (such as SW).

“…Even though, growth of Typha spp. under wastewater conditions has been well studied, most studies were conducted in the temperate climate [36][37][38][39][40][41]. Us-ing that information as guidelines may not be suitable for the CWs in the tropical regions as the local climate is different.…”

Constructed wetlands are an eco-friendly technology used for decades for treating various types of wastewater. To gain new insight into plant selection for wastewater treatment systems in tropical areas, this research investigated growth and ecophysiological responses of Typha angustifolia to different concentrations of anaerobic digester effluent from a swine farm and assessed their influence on wastewater treatment effectiveness. Twelve plants (n = 4 per treatment) were separately grown in 3 concentrations of wastewater (25% and 50% diluted wastewater and undiluted wastewater). All plants grew well in all concentrations. However, the plants tended to have reduced root biomass, root length and decreased pigment contents when exposed to high concentrations. High removal efficiency for electrical conductivity, total dissolve solids, total suspended solids, biochemical oxygen demand, chemical oxygen demand, ammonium nitrogen and orthophosphate was found (73%, 70%, 93%, 99%, 82%, 99% and 80%, respectively, from undiluted wastewater). The dissolved oxygen concentration in the anaerobic digester effluent increased over time because of released root oxygen. The study showed that T. angustifolia developed aerenchyma in its root cortex even under stress conditions. This ability makes this plant tolerant to high strength wastewater. Furthermore, oxygen released from its roots also supports growth of microorganisms and enhances microbial biodegradation processes leading to highly efficient treatment systems.

“…Membrane lipid peroxidation is a major contributor to these alterations, which presumably can lead to further deleterious consequences such as inhibition of ATPases [ 11 , 12 ]. Malondialdehyde (MDA) is one of the major products of membrane lipid peroxidation and has been used as an indicator of membrane lipid peroxide levels [ 13 , 14 ]. Additionally, in response to adverse conditions (e.g., dry, high, or low temperature, waterlogging), antioxidant enzymes such as superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) are produced to remove active oxygen radicals [ 15 ].…”

Urea application promotes amino acid metabolism and membrane lipid peroxidation in Azolla

et al. 2017

A pot experiment was conducted to evaluate the effect of urea on nitrogen metabolism and membrane lipid peroxidation in Azolla pinnata. Compared to controls, the application of urea to A. pinnata resulted in a 44% decrease in nitrogenase activity, no significant change in glutamine synthetase activity, 660% higher glutamic-pyruvic transaminase, 39% increase in free amino acid levels, 22% increase in malondialdehyde levels, 21% increase in Na+/K+- levels, 16% increase in Ca2+/Mg2+-ATPase levels, and 11% decrease in superoxide dismutase activity. In terms of H2O2 detoxifying enzymes, peroxidase activity did not change and catalase activity increased by 64% in urea-treated A. pinnata. These findings suggest that urea application promotes amino acid metabolism and membrane lipid peroxidation in A. pinnata.
